A window focus state may include at least one selected from an input event reception standby state related to a corresponding window, an image signal output related to the corresponding window, an audio signal output related to the corresponding window, activation of a communication unit related to the corresponding window, and application of screen effect related to the corresponding window.

According to various embodiments, the electronic device 100 may adjust the window focus if window switching in which a specific window position is exchanged with another window position occurs. According to various embodiments, the electronic device 100 may resize the multi-window when an event occurs which is related to a virtual handler presented in the display module 140 in relation to resizing the multi-window. In this process, the electronic device may automatically adjust window focus in correspondence to the resized multi-window.

The multi-window may have an identical structure or different structures according to a kind of an executed program in various embodiments. For example, windows may have different template structures for each program type such as an application or widget. Alternatively, a size of an area in a window, arrangement or disposition of a plurality of areas, the number of areas, and a shape or the number of virtual key buttons included at least one area may be differently, similarly, or identically defined for each program.

A multi-window environment may have a type where at least two among a plurality of windows are respectively disposed on divided screen areas in an embodiment. The plurality of windows may be mutually resized in correspondence to adjustment of a handler (or virtual handler). For example, the handler may be disposed between the first and second windows in a state where the first and second windows are disposed on the display module 140. For example, if a first window is resized in correspondence to a handler manipulation event, a second window may be resized to offset the size of the first window.

For example, the multimedia module 130 may transmit the audio signal received from the control module 160 to a speaker SPK. The multimedia module 130 may deliver an audio signal such as a voice received from a microphone MIC to the control module 160. The multimedia module 130 may convert the audio signal such as the voice received from the microphone into a digital signal and deliver the digital signal to the control module 160.

According to an embodiment, the multimedia module 130 may output an audio signal related to a specific window in an environment where multi-window is output on the display module 140. Here, the multimedia module 130 may output an audio signal of a focused specific window among the multi-window. If the window focus is changed to another window, the multimedia module 130 may output an audio signal related to the changed window.

According to various embodiments, when an operation related to handler manipulation or window switching occurs in the multi-window output environment, the multimedia module 130 may output a corresponding sound announcement or sound effect. In addition, when a new window is additionally output in the multi-window environment, the multimedia module 130 may automatically output an audio signal related to the newly output window. Alternatively, the multimedia module 130 may output an audio signal related to a window resized greater than a designated size through handler manipulation. An audio signal output scheme for the plurality of windows being output on the display module 140 may be adjusted according to a designer's scheme or user setting, or an audio signal output may be omitted.

The display module 140 may display (or output) at least one of various windows corresponding to functions processed by the electronic device 100. For example, if the electronic device 100 is in a voice call mode, a User Interface (UI) or Graphic User Interface (GUI) related to the voice call is displayed in a window type. In addition, if the electronic device 100 is in a video call mode or a capturing mode, the display module 140 displays captured or/and received images, UI, or GUI in a window type. According to an embodiment, the display module 140 displays application windows for various functions (or applications, or programs) executed in the electronic device 100. Furthermore, the display module 140 activates and displays a virtual input device (for example, a virtual touch pad) according to a control by the control module 160 in the application window, and deliver a signal input though the virtual input device to the control module 160.

According to an embodiment, the display module 140 may output at least one application window in correspondence to the at least one application 151.

FIG. 2 illustrated a configuration of a control module explained in various embodiments of the present disclosure.

Referring to FIG. 2, the control module 160 may include an event collecting module 161, a window processing module 163, a multimedia processing module 165, and a communication processing module 167, but is not limited thereto.

The event collecting module 161 may collect events occurring in the electronic device 100. For example, the event collecting module 161 may collect input signals occurring in the input module 120 as events. The event collecting module 161 may control power supplying to the touch panel in relation to input function support of the display module 140. The event collecting module 161 may collect touch events occurring in the display module 130 having the input function. If the electronic device 100 supports speech recognition and command function, the event collecting module 161 may accordingly activate the microphone and collect speech recognition event. If the electronic device provides various sensors, the event collecting module 161 may collect sensor information corresponding to a gesture as an event. For example, the event collecting module 161 may collect as an event at least one piece of sensing information such as acceleration sensing information, geo-magnetic sensing information, contact or pressure sensing information which occurs in at least one sensor. The events collected by the event collecting module 161 may provide to the window processing module 163.

According to an embodiment, the event collecting module 161 may collect touch events in relation to handler manipulation in a state where multi-window and handler are output. The event collecting module 161 may collect touch events instructing a position change between a specific window and another window in an environment where the multi-windows are disposed. The event collecting module 161 may collect touch events occurring on the focused window.

The window processing module 163 may be a module supporting a function process of each window. The window processing module 163 may process a function related to a specific window according to an event provided by the event collecting module 161. For example, if receiving an event for requesting execution of a first function from the event collecting module 161, the window processing module 163 may allocate a processor (or a system resource) to a first function process. In addition, if receiving an event for requesting execution of a second function from the event collecting module 161 in a state where the first function is being executed, the window processing module 163 may allocate a processor for the second function process. The window processing module 163 may deliver a specific event received from the event collecting module 161 to the processor related to the first function process or the process related to the second function process. Then the processor related to the first function process may perform the first function in correspondence to the delivered event. In addition, the processor related to the second function process may perform the second function corresponding to the delivered event.

According to an embodiment, the window processing module 163 may output a handler if receiving a request for an output of the multi-window. The handler may be disposed at least one point on a boundary area of the multi-window. The window processing module 163 may receive a touch event related to the handler manipulation from the event collecting module 161. The window processing module 163 may resize the multi-window in correspondence to a touch event in relation to the handler manipulation. If a size of a specific window is not smaller than a certain size in the resizing process of the multi-window, the window processing module 163 may control so that the corresponding window is focused. If the size of the specific window is not greater than the certain size in the resizing process of the multi-window, the window processing module 163 may control so that the corresponding window is deactivated. According to an embodiment, the window processing module 163 may invalidate or neglect a touch event occurred on the deactivated window.

The window processing module 163 may receive a touch event related to position adjustment of the specific window, for example, a switching event, from the event collecting module 161. The window processing module 163 may adjust disposition positions between specific windows in correspondence to the window switching event.

The multimedia processing module 165 may receive window focusing information from the window processing module 163. The multimedia processing module 165 may confirm which window is focused by confirming the window focusing information. The multimedia processing module 165 may confirm whether there is an audio signal to be output in relation to the focused window. If there is the audio signal related to the focused widow, the multimedia processing module 165 may control so that the corresponding audio signal is to be output therethrough. If there is an audio signal related to a previously focused window, the multimedia processing module 165 may limit an output of the corresponding audio signal. According to various embodiments, if there is not an audio signal related to the focused window, the multimedia processing module 165 may control so that the audio signal of the previously focused window is output.

The communication processing module 167 may receive window focusing information from the window processing module 163. The communication processing module 167 may confirm whether there is a communication function related to the focused window by confirming the window focusing information. If there is the communication function related to the focused window, the communication processing module 167 may support the corresponding communication function. For example, a window focus related to a short range communication function may be changed into the window focus related to a broadcast reception function. In this case, the communication processing module 167 may control so that a short range communication unit related to the short range communication function is transitioned to a standby state or be deactivated. The communication processing module 167 may activate a broadcast reception unit related to the broadcast reception function.

According to various embodiments, the communication processing module 167 may release, create or reconnect a communication channel according to whether a focus is performed in relation to a web access function. For example, if a corresponding web access function window is focused in relation to the web access function, the communication processing module 167 may create or reconnect a communication channel with a specific server device. In addition, if the focus of the web access function window is released, the communication processing module 167 may release the communication channel.

FIG. 3 illustrates a multi-window control method of an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 3, according to an embodiment, when a specific event occurs, in operation 301, the control module 160 may confirm whether the corresponding event is a multi-window related event (for example, the multi-window event may be event to output plural windows on the display module). When the event occurred in operation 301 is not the multi-window related event, the control module 160 may proceed to operation 303 and support function performance according to a kind and characteristics of the corresponding event. For example, the control module 160 may output a window according to the specific function performance on the display module 140. Alternatively, the control module 160 may output an audio signal according to playback of a specific sound source or support a specific communication function performance.

When the multimedia related event is confirmed to occur in operation 301, the control 160 may perform a multi-window or handler output in operation 305. The multi-window related event may be an event requesting a multi-window output from the display module 140. For example, when an event occurs which selects an icon or a menu item set to simultaneously execute a plurality of apps, the display module 140 may output multi-window. Alternatively, when an application execution request is additionally occurs in a state where one window according to a specific application execution is output, multi-window may be output on the display module 140. Here, the multi-window may be two or more windows. The handler may be disposed at least one point among corners or edges of windows included in the multi-window. According to an embodiment, the handler may be disposed at least one point among edge points at which three or more windows face each other. When the three or more windows face each other, the handler may be disposed at a position at which three or more windows face each other, for example, a specific corner point. The handler may support a function process related to resizing of the multi-window. If the handler moves to a certain point, the multi-window may be resized around the moved point of the handler.

In operation 307, the control module 160 may confirm whether a handler related event occurs. For example, the control module 160 may confirm whether a touch event occurs at a position where the handler is output on the touch panel. Alternatively, the control module 160 may confirm whether an input event occurs from a key button or a key map related to the handler manipulation or other various input units.

When the handler related event occurs in operation 307, the control module 160 may perform a multi-window display control and focusing process in operation 309. In this process, the control module 160 may output guiding information for guiding a handler movement direction in correspondence to the handler selection event. The control module 160 may perform resizing of the multi-window in real time according to movement of the handler. For example, the control module 160 may reduce or increase a size of at least one specific window by moving at least one of edges of the plurality of windows related to the handler in correspondence to the movement of the handler. The control module 160 may reduce or increase a size of at least one other window in correspondence to the reduction or increase of the size of the specific window. According to an embodiment, the control module 160 may adjust focus if the specific window is resized to a specified size or greater in a process of controlling display of the multi-window. For example, if an unfocused window is resized to the specified size or greater, the control module 160 may control so that the resized window is focused. If the focused window is resized to the specified size or smaller, the focus of the corresponding window may be released. The control module 160 may control a process of at least one selected from an input event reception standby state according to the focusing process, an audio signal output process, communication channel formation, and a communication module activation state.

According to various embodiments, when an operation of touching the handler occurs, the control module 160 may transit a display state of the multi-window to a multi-window state of a predefined ratio. For example, when the touch event (such as a double tap event, pinch zoom event, or long touch event) predefined on the touch panel on which the handler is disposed occurs, the control module 160 may equally divide the display module 140 and dispose the multi-window on the equally divided areas. At this point, the control module 160 may control so that a window focused before touching the handler is maintained as the focused state. Alternatively, the control module 160 may control so that a specific window is focused according to a predefined scheme.

When the event occurred in operation 307 is not the handler related event, the control module 160 may confirm whether the corresponding event is a switching event in operation 311. The switching event may be an event that changes a specific window position and another window position. For example, the switching event may be an event for moving the specific window for such as a drag event, sweep event, or flick event to another position on the display module 140. Furthermore, in an embodiment, the switching event is not limited to a kind of the above-described event. For example, a pinch zoom event for selecting a plurality of windows or an event for sequentially selecting a different window from the specific window may be the switching event. According to various embodiments, the control module 160 may support to create a window switching event through various schemes providing a menu when selecting the specific window or providing a state where another window to be changed may be designated when selecting the specific window.

When the window switching event occurs in operation 311, the control module 160 may perform a window switching process in operation 313. According to an embodiment, if a long touch event (a holding touch event maintained for a certain time or longer on an area where a specific window is disposed) occurs in relation to the specific window among the multi-window, the control module 160 may designate the corresponding window as a state capable of switching. In addition, the control module 160 may change the designated window position according to a drag event occurring after the long touch event. For example, the control module 160 may control a position change of the designated window and a window at least a portion of which is designated overlaps or that a certain portion thereof overlaps, according to a drag event direction and a moving distance.

When the switching event does not occur in operation 311, the control module 160 may process an operation according to the corresponding event in operation 315. For example, the control module 160 may process functions related to a corresponding event for an event occurring on a focused specific window. Alternatively, in case of an event requesting a focus change for the specific window, the control module 160 may perform a focus change according to the corresponding event.

The control module 160 may confirm whether an event related to a function completion occurs in operation 317. When the event related to the function completion occurs, the control module 160 may remove the multi-widows from the display module 140. In this process, the control module 160 may terminate a function related to the removed windows or transit to a standby state (or idle state). When the event related to function completion does not occur, the control module 160 may support to proceed before operation 305 and re-perform thereafter processes.

According to various embodiments, the multi-window control method according to an embodiment may include a process of displaying a plurality of windows, a process of changing a size of any one specific window among the plurality of windows in correspondence to an event occurrence, and a process of altering a focus that performs a function related to the specific window if the size of the specific window is extended to a specified size or greater.

According to various embodiments, the changing operation may include at least one operation selected from an operation of reducing a size of another window in correspondence of size extension of the specific window, an operation of releasing the altered focus if sizes of the other windows are reduced to the specified size or smaller, an operation of transitioning input state related to size-reduced windows to a deactivation state, if the sizes of the other windows are reduced to the specified size or smaller, and an operation of changing display effects of size-reduced windows, if the sizes of the other windows are reduced to the specified size or smaller.

According to various embodiments, the method may further include an operation of receiving an event related to the size reduced windows, an operation of extending, to the specified size, a window designated by the window related event, and an operation of altering a focus to the designated window.

According to various embodiments, the method may further include an operation of outputting a handler controlling to resize the windows to a boundary area where the plurality of windows are disposed.

According to various embodiments, the changing operation may further include an operation of resizing the specific window in correspondence to movement of the handler.

According to various embodiments, the method may further include an operation of receiving a handler touch event, an operation of resizing the plurality of windows in a predefined ratio and disposing them. The method may further include an operation of maintaining focus of the specific window.

According to various embodiments, the method may include an operation of receiving a handler movement event, an operation of extending a size reduced window in correspondence to the handler movement event, and an operation of changing the focus if the extended window is extended greater than a specified size.

According to various embodiments, the method may further include an operation of outputting guiding information instructing a specified size of a window satisfying the focus alteration.

According to various embodiments, the method may further include an operation of disposing a menu item related to the specific window on an area adjacent to a boundary area of the windows, an operation of receiving a window switching event, an operation of moving the specific window to a position where another window has been disposed in correspondence to the window switching event, an operation of moving the menu item with the specific window and disposing the menu item on the area adjacent to the boundary area of the windows.

FIG. 4 illustrates a double (dual) window operation of the multi-window according to an embodiment of the present disclosure.

Referring to FIG. 4, the display module 140 of the electronic device 100 may output multi-window including windows 401 and 402 as shown in a screen 41. The windows 401 and 402 may be disposed at certain areas divided from an entire screen of the display module 140. One edge of the window 401, for example, a right edge and a left edge of the window 402 may face each other. The display module 140 may output a handler 410 between the windows 401 and 402. The handler 410 may be disposed at an area where the windows 401 and 402 face each other. Here, the window 402 may be in a state of being focused. A specific touch event or a specific menu selection may occur to allow the window 402 to be focused. Alternatively, in an operation where the windows 401 and 402 are output on the display module 140, the window 402 may alter a focus by default. Alternatively, when the window 402 is output and multi-window is configured in a state where the window 401 is output in full screen of the display module 140, the window 402 output later in time may be automatically focused.

When receiving an event for selecting the handler 410 output on the display module 140, for example, a touch event occurring on a position at which the handler 410 is disposed, the control module 160 may output the guiding information 420 as shown. At this point, the guiding information 420 may be information for instructing a window size to be had in order for the window 401 to be automatically focused. For example, as in the screen 43, the size of the window 401 may be extended to an area instructed by the guiding information 420 by moving the handler 410. The control module 160 may be automatically focused if the size of the window 401 is extended to a specified size or greater. The display module 140 may reduce the size of the window 402 in correspondence to the size extension of the window 401. The control module 160 may release the focus of the corresponding window as shown, if the window 402 is reduced to a specified size or smaller. If the window 402 is reduced to the specified size or smaller, the control module 160 may process to have an input deactivation state. The input deactivation state may be a state where a specific touch event occurring on a window having the specified size or smaller is neglected.

In a state of the screen 43, when a predefined specific event 412 occurs, the control module 160 may change the multi-window environment as in a screen 45. For example, when a double tap event 412 occurs on the window 402 reduced to the specified size or smaller, the control module 160 may resize the window 402 to have a certain size or greater on the display module 140. For example, the control module 160 may control so that the window 402 has a greater area than the window 401. Alternatively, the control module 160 may control so that the window 402 is to be displayed in full screen. In this process, the control module 160 may control so that the window 402 is focused. The control module 160 may control so that an input (e.g., a touch input) to the window 401 becomes a deactivation state.

When a specific event 411 occurs which is predefined in a screen state 43, the control module 160 may control a multi-window change as in screen 47. For example, when a double tap event 411 occurs on a position at which the handler 410 is disposed, the control module 160 may control so that the windows 401 and 402 have the same display size on the display module 140. In this process, the control module 160 may control the window 401 so as to be focused. Although the specific events 411 and 412 are described as double tap events, various embodiments are not limited thereto. For example, the specific event may include various events such as a tap event, long touch event, and pinch zoom event.

The control module 160 may change a display effect according to a focus change. For example, the control module 160 may display borders of the focused window brighter than before or other windows. Alternatively, the control module 160 may change border color or shape of the focused window. Alternatively, the control module 160 may control so that a screen element enabling to recognize the focus is output on the border of the focused window.

In the above description, the specific event is exemplified as a double tap, but the present disclosure is not limited thereto. For example, the double tap event may be replaced with a pinch zoom event, a tap event touching multi-points, a swipe or sweep event. In addition, the windows 401 and 402 are transitioned to a state where a screen is equally divided and displayed according to the specific event occurs, the present disclosure is not limited thereto. For example, when the specific event occurs, the control module 160 may return to a state rightly before changed to screen 43, for example, a state 41.

FIG. 5 illustrates a quad window operation of multi-window according to an embodiment of the present disclosure.

Referring to FIG. 5, the display module 140 may output four windows 501, 502, 503, and 504. The four windows 501, 502, 503, and 504 may be respectively disposed on certain areas of the equally divided display module 140 as in a screen 51. The display module 140 may output a handler 510 at a certain point at which the four windows 501, 502, 503, and 504 are disposed. According to an embodiment, the handler 510 may be disposed at a point where all the windows 501, 502, 503, and 504 are simultaneously connected. The electronic device 100 outputting the four windows 501, 502, 503, and 504 may alter a focus to the window 502 according to an input event or specified schedule information. The focus altered window 502 may have a screen activation state. The electronic device 100 may output an image signal related to the window 502 on an area of the window 502. The electronic device 100 may output an audio signal related to the window 502 through the multimedia module 130. When a communication module related to the window 502 is present, the electronic device 100 may control so that the corresponding communication module has an activation state. When the handler 510 is selected for resizing a specific window, the display module 140 may output guiding information 520 as shown in a screen. The guiding information may be displayed across at least a portion of the windows 501, 502, 503, and 504. The guiding information may be information instructing a minimum size to be changed in relation to focus alteration of the specific window.

A touch event related to movement of the handler 510 may occur. In addition, the handler 510 may be moved to a point of the guiding information 520 at a position where the window 502 is disposed as shown in a screen 53. In correspondence to this, the window 503 may be extended to a specified size or greater. The control module 160 may automatically alter a focus to the window 503 having the specified size or greater. The windows 501, 502, and 504 may be reduced to a specified size or smaller. The control module 160 may change the windows 501, 502, and 504 to an input deactivation state. In this process, the control module 160 may change display effects of the windows 501, 502, and 505 having the specified size or smaller. For example, the control module 160 may inverse color of or apply a shadow effect to at least one of the windows 501, 502, and 504 having the specified size or smaller.

In a screen state 53, a predefined handler related event 511 may occur. For example, in relation to the handler 510, a double tap event for touching the handler 510 twice may occur. When the predefined handler related event occurs, the control module 160 may control so that the windows 501, 502, 503, and 504 are displayed in a size of a certain predefined ratio. For example, the control module 160 may control so that the windows 501, 502, 503, and 504 are equally displayed as in a screen 55. According to various embodiments, the control module 160 may control so that the windows 501, 502, 503, and 504 are output in unequal sizes on the display module 140. Alternatively, the control module 160 may return to a screen state right before the screen state 53. According to one a embodiment, the control module 160 may control so that a specific window 503 remains focused just like the same state before the handler related event 511 occurs.

According to various embodiments, in relation to a window having a specified size or smaller, a predefined window related event 512 may occur. For example, a long touch event or a double tap event 512 may occur on the window 502. When the specified window related event 512 occurs, the control module 160 may dispose the windows 501, 502, 503, and 504 so as to have sizes of a predefined ratio. In this process, the control module 160 may control so that the window 502 corresponding to the window related event 512 is focused. Accordingly the control module 160 may release the focus of the window 503.

According to various embodiments, at least one of equally divided windows 501, 502, 503 and 504 may have an input activation state. For example, the control module 160 may alter the focus to the window 502 on a screen 57, but touch events occurring on the windows 501, 503 and 504 may be normally collected and processed. Accordingly, when a touch event occurs which is for selecting a specific object disposed on the window 501, the control module 160 may process the touch event occurring on the window 501. At this point, the control module 160 may control so that the window 501 has focus altered to the window 502. According to an embodiment, the control module 160 may output an audio signal related to the window 502, limit the audio signal related to the window 502 when a touch event occurs on the window 501, and then output an audio signal related to the window 501. Here, the window 503 whose focus is released may recognize a touch event occurring the corresponding window as a valid event like other windows, and have an input activation state capable of function-processing according to the corresponding event.

Furthermore, in the screen state 53, the windows 501, 502, and 504 may have an input deactivation state. In addition, until when a predefined specific touch event occurs, or a specific menu selection or a specified window size is obtained, the windows 501, 502, and 504 having a specified size or smaller may maintain the input deactivation state.

FIG. 6 illustrates a quad window operation of multi-window according to an embodiment of the present disclosure.

Referring to FIG. 6, the display module 140 may display a window 603 that is focused and windows 601, 602, and 604 having specified size or smaller as in a screen 61. The display module 140 may output a handler 610 at a point where corners of all the windows 601, 602, 603, and 604 are connected. The handler 610 may support to resize all the windows 601, 602, 603, and 604.

When an event 611 related to the handler 610, for example, an event 611 for long-touching the handler 610 in relation to the handler 610, the control module 160 may output guiding information 620 as in a screen 63. The guiding information 620 may instruct a size to be had in order for any one of all the windows 601, 602, 603, and 604 to be focused.

In the screen 63, an event for extending a size of the window 601 may occur. For example, a window related event 612 determined on an area where the window 601 is disposed occurs, or the handler 610 may be moved to a position allowing the window 601 to be extended in succession to the long touch event 611. According to an embodiment, when the handler 610 is moved downward, the size of the window 601 may be extended as in a screen 65. The display module 140 may output disposition of windows that the size of the window 601 is extended as in the screen 65. If the window 601 is extended to a specified size or greater, the control module 160 may control so that the window 601 is focused as in the screen 65. As the window is extended to a certain size, the sizes of the windows 602, 603, and 604 may be reduced to the specified size or smaller. The control module may control so that the windows 602, 603, and 604 having the specified size or smaller are in the input deactivation state. At this point, the control module 160 may change display effects of the windows 602, 603, and 604 having the specified size or smaller as shown.

In the screen 63, an event for extending the size of the window 604 may occur. For example, the handler 610 may be moved in a left direction of the screen, which is a direction that the window 604 is extended according to the guiding information 620, or a specific designated touch event may occur on an area on which the window is disposed. The control module 160 may extend the size of the window 604 as shown in the screen 67 according to the occurred event. The control module 160 may control so that the window 604 is focused at the time if the size thereof is changed to a specified size or greater. The control module 160 may control so that the windows 601, 602, and 603 having a specified size or smaller are in the input deactivation state.

FIG. 7 illustrates window switching operation of double windows of multi-window according to an embodiment of the present disclosure.

Referring to FIG. 7, the display module 140 may display windows 701 and 703 as in a screen 71. A handler 710 may be output between the windows 701 and 703. The control module 160 may output a menu item 705 on the window 701 according to occurrence of an input event or a touch event. The menu item 705 may be disposed on a boundary area between the windows 701 and 703. For example, the menu item 705 may be disposed on an area of the window 701, which is adjacent to an area faced the windows 701 and 703. Here, the menu item may be a menu item related to a currently focused window. Accordingly, the menu item output on the display module 140 may be a menu item related a window focused at the time when an event related to the handler 710 occurs or an event related to a menu item call occurs.

The menu item 705 may include a window switching item. When the window switching item is selected, the windows 701 and 703 may be in a window switching standby state. According to occurrence of an event that moves the window 701, the control module 160 may move the window 701 to a position at which the window is disposed 703 as shown in a screen 73. In correspondence to this, the control module 160 may move the window 703 to a position at which the window 703 is disposed. The control module 160 may control so that, in the window switching operation, the menu item 705 is moved and output on the window 701. In this process, the control module 160 may be disposed at a position adjacent to the boundary area of the windows 703 and 701 as shown in the screen 73.

According to various embodiments, the control module 160 may recognize an event for long-touching the window 701 as the window switching event. Accordingly, when the long touch event occurs on the window 701, the control module 160 may change the window 701 to a state where switching is enabled. The control module 160 may swap the position of the window 701 with the position of the window 703 in correspondence to occurrence of a drag event.

FIG. 8 illustrates a window switching operation of quad windows of multi-window according to an embodiment of the present disclosure.

Referring to FIG. 8, the display module 140 may output windows 801, 802, 803, and 804 in correspondence to a multi-window output request as shown in a screen 81. The display module 140 may output a handler 810 to a boundary area of the windows 801, 802, 803, and 804. For example, the display module 140 may output the handler 810 at a position at which vertexes of the windows 801, 802, 803, and 804 are connected to each other. The control module 160 may alter a focus to a specific window, for example, the window 801 among the windows 801, 802, 803, and 804.

The control module 160 may output a menu item 805 on the window 801 in correspondence to an event occurrence or by default. Alternatively, the control module 160 may output a menu item related to a specific window in correspondence to an event occurrence related to manipulation of the handler 810. For example, the control module 160 may output a menu item related to a currently focused window or a menu item related to a window at a predefined specific position.

The menu item 805 may be disposed on a boundary area between the window 801 and another window. For example, the menu item 805 may be disposed at a position adjacent to a boundary area between the window 801 and the window 803. The menu item 805 may include a window switching item. When the window switching item among the menu item 805 is selected, the control module 160 may change the window 801 in a position movable state.

As in the screen 83, an event for moving the window 801 to a position at which the window 804 is disposed may occur. The control module 160 may move the window 801 to the position at which the window 804 is disposed in correspondence to occurrence of the corresponding event and moves the window 804 to a position at which the window 801 is disposed. In this process, the control module 160 may move the menu item 805 together. In addition, the menu item 805 may be automatically disposed on an area adjacent to a boundary area between the window 801 and another window. In a screen 85, the menu item 805 may be disposed on an area adjacent to a boundary area between the window 801 and window 802.

As described above, double windows and quad windows are exemplified as the multi-window, but the present disclosure is not limited thereto. For example, according to various embodiments, the multi-window may include various numbers of windows such as 3, 5, 6, 8, and 9. Accordingly, a division line for dividing the multi-window may equally or unequally divide the display module 140, and be included in plurality.
